There was a 'hangar' in which a Whirlwind with blades folded could be inserted. What provided the muscle power to get helicopters from the single adjacent HLS along the albeit very short (1.5 aircraft length) taxi track into the hangar?
In the absence of helistart I assume one of the quite small hand operated motorised tugs that looked like something you buff the floors on a bull night with. (only with wheels x3)
